“I purchased my 2016 Buick Cascada in 2017, in the summer of 2018 I noticed the paint chipping off all 4 of my rims. Then in december of 2020 I noticed the back window started to become unattached from the convertible top. The vehicle is now out of warranty and the dealership tells me I need to replace the entire top, which is absolutely ridiculous. I paid $38,000 for a vehicle that is falling apart. I don't understand why general motors it's not held responsible for this?”
NHTSA complaint #11396566, filed 2021-02, 50,000 miles“The rear glass window is lifting on the bottom left corner. My husband just noticed it one day. A service bulletin was released by GM in november, 2019 regarding this issue. My insurance won't cover it as it was not caused by an outside force. Safety hazard: if I drive with my windows open and top up, I'm afraid the pressure will cause the window to detach, which would injure any vehicle behind me. This should be a GM recall. The glass can not be replaced without replacing the entire soft top.”
NHTSA complaint #11339734, filed 2020-07, 36,000 miles“My rear window of my car is becoming unglued from the top. I talked to the GM dealership nearby, and they told me I needed a new top. There was a memo put out in 2019 stating that this was happening due to not having enough primer from the manufacturer. This is a safety hazard. If my window falls out, it can create a crash and harm any vehicle behind me. If GM knew this part was bad because of a manufacturer, they should be liable to fix the problem.”
NHTSA complaint #11455952, filed 2022-03“My convertible top is not lining up with the windows. When it rain water on the floor . U don’t see where it’s coming from . I just see large amount of water”
NHTSA complaint #11580207, filed 2024-03“Buick Cascada back window on the convertible tops coming apart, causing flooding inside the car, also there's a danger the window will come out driving down the road. Buick refuses to do anything.”
